Electromagnetic slurry magnetic separator

Abstract

The invention discloses an electromagnetic slurry magnetic separator. The electromagnetic slurry magnetic separator comprises a magnetic separation device, a splitting device, a converging device anda cooling device. The magnetic separation device comprises a coil arranged in a wire box, and an upper magnetic pole, a magnetic medium device and a lower magnetic pole communicated with one another to form a magnetic separation cavity are arranged in an air gap in the middle of the coil; the splitting device is arranged above the upper magnetic pole and comprises a multi-pipeline splitting interface, a splitter and a water separator; the multi-pipeline splitting interface comprises a plurality of splitting pipes communicated with the splitter and the magnetic separation cavity and a pluralityof water dividing pipes communicated with the water separator and the magnetic separation cavity; the converging device is arranged below the lower magnetic pole, is substantially as same as the splitting device in structure, and the two are symmetrical; and the cooling device adopts a forced oil circular cooling mode. According to the electromagnetic slurry magnetic separator, a pipeline channelwhere slurry and flushing water are separated, a flow is distributed uniformly, the concentrate grade and purity are high, and waste of the slurry is small; the cooling effect of the coil is good, the diameter of the coil is great, the exciting power is small, the ton energy consumption is low, the output is high and the occupied area is small.

Description

technical field [0001] The invention relates to the technical field of magnetic separation equipment, in particular to a large-scale electromagnetic slurry magnetic separator. Background technique [0002] For non-metallic minerals, iron and other magnetic impurities will affect the quality of minerals, such as: whiteness, concentrate rate, purity, etc. of kaolin. Therefore, the ability of magnetic separation equipment to remove ferromagnetic impurities has a direct impact on the quality of non-metallic minerals. With the increasing demand for high-end non-metallic mines, there is an urgent need for large-scale electromagnetic slurry magnetic separators. [0003] The existing electromagnetic slurry magnetic separator generally adopts a common pipeline channel for slurry and flushing water, which makes the fluid distribution uneven, the slag discharge is not thorough, the concentrate grade is reduced, and the purity of the concentrate is affected. Moreover, the diameter of ...

[0003] The existing electromagnetic slurry magnetic separator generally adopts a common pipeline channel for slurry and flushing water, which makes the fluid distribution uneven and the slag discharge incomplete, which reduces the concentrate grade and affects the purity of the concentrate

In addition, the diameter of the sorting chamber is small, the output of a single unit is low, and the number of units required for capacity expansion has the disadvantages of large energy consumption and large space occupation.
